PAINT.

130S884L Specification of Letters Patent.

No Drawing. Application filed August 3, 1917. Serial No. 184,207.

T 0 all whom it may concern:

Be it known that I, WALTER E; WRIGHT, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a. new and useful Paint, of which the following is a specification.

This invention relates to an improved paint more especially adapted for an undercoat in painting and comprising a suitable metallic pigment, tung oil, a semi-drying or non-drying oil adapted to retard the drying of the tung oil, a. drying oil other than tung oil, as, for instance, linseed oil, and a thinning vehicle, such, for instance, as turpentine or petroleum distillate.

The object of this invention is to produce a paint which is not only more especially adapted for an undercoat in painting, but which insures a slow-drying undercoat and produces a better surface to receive the finishing coat of paint and is more alkaliresisting, more easily applied and more durable than undercoats of paints heretofore used.

The present invention more especially pertains to a palnt comprlsing a sultable metallic pigment, such, for instance, as white lead or oxid of zinc. A lead pigment is prefand elastic skin and is therefore a most de- 7 sirable oil as a binder in making my improved paint. I would here remark that the drying of the linseed oil and tung oil, and more especially the drying of the tung oil,

is retarded by the use of soja bean oil or cotton-seed oil or parafiin oil. 7 The use of soj a bean oil in retarding the drying of the timg oil is preferred, but I would here r'emark that soj a bean oil of itself'dries tacky and would be undesirable. and impractical without the presence of a suitable quantity of tung oil. Of course, my improvedpaint also comprises a suitable thinning vehicle,

such,- for instance, as tiirpentine or petro leum distillate.

In making my improved paint I preferably use the metallic pigment, the tung oil, the oil adapted to retard the drying of the tung oil, linseed oil as the drying oil other than tung oil, and the thinning vehicle substantially'in the proportion, by weight, of from four to fourteen parts of thetung oil, from seven to thirty-five parts ofthe oil adapted to retard the drying of the tung oil,

from nine to twelve parts of the linseed oil, and from eighteen to twenty-four parts of the thinning vehicle, to one hundred parts of the pigment.

Good results have been attained by me in using a lead or zinc pigment, linseed oil,

tung oil, soj a bean oil and a thinning vefour parts of the thinning vehicle to one hundred parts of the pigment. V

' Fairly goodresults have been attained by me in using a lead or zinc pigment, linseed oil, soja bean oil and athinning vehicle sub stantially in the proportion, by weight, of from nine to twelve parts of linseed oil, four parts of tun'g oil, seven parts of'so'ja' bean oil and from eighteen to twenty-four parts ofthe thinning vehicle to one hundredparts V of the pigment.

I Highly satisfactory results have been attained by me in using a lead pigment, linseed oil, tung oil, soja' bean oil and a thinning vehicle substantially in the proportion, by Weight, of about nine parts of linseed oil,

eight parts of tung oil, sixteen parts of soja bean oil and twenty-four parts of the thinning vehicle to one hundred parts of the lead pigment. 7 7 V Thebest results have'been attained by me in mixing the linseed oil and. the pigment and then thinning the mixture ofpigment and linseed oil byadding about one-half of the thinning vehicle to be used in making my improved paint and thereby placing said mixture in the best possible condition for the addition of the tungoil, soj a bean oil and the remainder of the thinning vehicle to be used. Thereupon, to attain the best results, the tung oil and the soja bean oil are mixed independently of the thinned mixture of linseed oil and pigment, and then the oil-mixture of tung oil and soja bean oil is added and mixed with the thinned mixture of pigment and linseed oil preparatory to adding the remainder of the thinning vehicle.

The most approved embodiment of my invention therefore consists in a suitably thinned paint which com-prises a thinned mixture comprising a lead pigment and linseed oil and also comprises an oil-mixture comprising tung oil and soj a bean oil, with the oils of said mixtures and the pigment substantially in the proportion, by weight,

of eight parts of the tung oil, sixteen parts of the soja bean oil and nine parts of the linseed oil to one hundred parts of the pigment.

I would here remark, however, that I have attained good results from a paint made by me and comprising a mixture comprising a lead or zinc pigment and linseed oil, an oilmixture comprising tung oil and paraflin oil, and a thinning vehicle, with the thinning vehicle, the pigment and the linseed oil substantially in the proportion,by weight, of from nine to twelve parts of linseed oil and from eighteen to twenty-four parts of the thinning vehicle to one hundred parts of the pigment, with the quantity of tung oil used equal, by weight, to more than three per cent. of the amount of pigment used, and with the quantity of paraflin oil used not less, by weight, than the quantity of tung oil used.

hat I claim is:

1. A paint comprising a metallic pigment,

the tung oil, and from nine to twelve parts of the second-mentioned drying oil, to one hundred parts of the pigment.

2. A paint comprising a metallic pigment, tung oil, soj a bean oil, and a drying oil other than tung oil, substantially in the proportion, by weight, of from four to fourteen parts of the tung oil, from seven to thirt five parts of the soj a bean oil and from nine to twelve parts of the second-mentioned drying oil, to one hundred parts of the pig ment.

3. A paint comprising a metallic pigment, tung oil, an oil adapted to retard drying of the tung oil, and a drying oil other than tung oil, substantially in the proportion, by weight, of about eight parts of the tung oil, about sixteen parts of the oil adapted to retard drying of the tung oil, and about nine parts of the second-mentioned drying oil, to one hundred parts of the pigment.

4. A paint comprising a metallic pigment, tung oil, soj a bean oil, and a drying oil other than tung oil, in the proportion, by weight, of about nine parts of the last-mentioned oil, about sixteen parts of the soja bean oil and about eight parts of the tung oil, to one hundred parts of the pigment.

5. A paint comprising a metallic pigment, tung oil and an oil adapted to retard drying of the tung oil and a drying oil other than tung oil, with the second-mentioned drying oil and the pigment substantially in the proportion, by weight, of from nine to twelve parts of said second-mentioned drying oil to one hundred parts of the pig ment, with the quantity of tung oil used equal, by weight, to more than three and not over about fourteen per cent. of the amount of pigment used, and with the quantity of oil used to retard drying of the tung oil not less, by weight,'than the quantity of tung oil used.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.
